My presentinventimi has ref'erence to a pulley designed to beconnectedto-anymoter that has a ball and 1 universal; -joint; such-forinstance, 'as the universal jointbetweenthe engine and drive shafts ofan =azutomebrle, so that "either a disconnected or disused-type of suchmachines may be success'fullyem- 'ployed as'a stationary motor fordrivilig A suitable machinery that is hitched to the .pulley. to r L I Afurther object the provision {of' afpulley for this purpose whichhasanti-frictional bearings of a type to insure'thefree-turning thereof,and that has removable rims, whereby the 4 cross sectional" diameter ftheppulley may be increased or decreased as occasion re qu Q1 4. o

To the attainment of the above broadly stated objects and others whichwill present themselves as the nature of the invention is betterunderstood, the improvement fur? ther resides in certain other novelfeatures of construction, combination and operative association ofparts, one satisfactory embodiment of which is disclosed'by theaccompany drawings.

In the drawings:

Figure 1 is a substantially central longitudinal sectional View throughthe improvement.

Figure 2 is an end view thereof.

Figure 3 is a sectional view approximately on the line 3-3 of Figure 1.

In Figure 1 of the drawings, there is illustrated a housed universaljoint 1 of the type employed between the drive and. the drivenshaft-s ofan automobile or like motor. The socket element of the universal jointis for distinction indicated by the numeral 2.

In carrying outmy invention I disconnect the outer half oft-he housingfor the universal joint, that is the portion thereof through which thedriven shaft passes, and bolt to the section of the housing that remainswith the motor a housing section 3 that is provided with a sleeveextension 5. As a matter of fact, the housing section 3 may be thatusually employed, in which in-.

stance, the sleeve 5, which originally provides the housing for thewheel drive for the driven shaft is cut away and has its outer endthreaded.

Passed through the sleeve 5 and having squared end received in thesocket 2 there is a shaft 6. This shaft has an outer disc head 7, andthe central portionv of the'head is bulged -ispacer element or washerand width v a second i nut 11 that. is a;lso screwedmmi the sleeve.-Themut' ll' abuts onexend efthe; bib" i'poi'tion l2' 'of a' conicalraceway element 13 -for oonica-Lbeari-ngs' 14. Thememberifi has itsinner endrcontacted by a collar :or bushing 15 thatsurreundsthe sleeve5,randtbiswol- I -lar also eontaets with the inner of-ia I -s'econdraceway or bearing lmember 'or .other conieal rollers 17. The hubportion -of-;the' member ltycontaets with the' housing 3. The outerelementsthat provide the-bear in'gs for therollers -17 are; in thenature oi -comparatively wide rings 1 8,-the

said rings havinginner' flared Greene-shaped bores, as clearly disclosedby Figure 1 of the drawings. The bearing members 16 and 18 the medium ofa split spring ring 20 that is received in an annular roove 21 1n theouter peripheral member or elly 22 of the pulley. The head 7 for theshaft 6 is secured to the felly member 22 throu h the medium of bolts23, as clearly disclose by the drawings.

The member 22 is provided with a de pression whose inner wall ispreferably circular and which provides a pocket for a key 24. The key;is designed to be received in a groove or ey-way 26 on the inner face orbore of a removable rim 27. The rim is thus locked to the pulley so thatthe same willturn with the pulley, and the rim is held from longitudinalmovement on the pulley through the medium of a removable element 28 thatis preferably in the nature of a headless screw and which enters adepression in the outer or peripheral member 22 of the pulley. V o i Thesimplicity of my construction and the advantages thereof will be, itisthought, understood and appreciated by those skilled in the art to whichsuch invention relates without further detailed description. It is to benoted that the head 7 of the shaft 6 being locked to the peripheralmember 22 will cause the end member, and the rim thereon to revolve withthe shaft. The outer bearing members 18 are preferably fixed to theperipheral member 22 to revolve therewith, but the inner bearings orraceways for the roller bearings are locked on surrounding the shaft,spaced bearing members fixed on the sleeve, 'an elongated ring memberproviding a felly surrounding the bearing members, bearing memberscarried by the felly, and affording a' race-Way With the first mentionedbearing members,'antifrictional elements in the race-Ways, meansconnecting the head of the shaft With the felly and a removable rimfixed on the felly.

2. In a pulley as herein described, a shaft designed to be driven by amotor and having an outer headed end, a fixed sleeve surrounding theshaft, spaced sectional bear- 2O ings removably fixed on the sleeve, afelly removably connected to the head of the shaft, and having inwardlydirected bearings thereon, anti-frictional rollers between V the'firstand second mentioned bearing members, means on the sleeve spacing thefirst mentloned bearlng members, means on the felly holdlng one of thefirst mentioned bearfirst mentioned housing section, bearing membersproviding inner elements of arace- Way arranged on the sleeve, means onthe sleeve spacing the bearing members and securing the same to thesleeve, a comparatively Wide ring member providing afelly, removablemeans securing the felly to the head of the shaft, bearing membersproviding the second elements of the race-vvays carried by the felly,frusto conical bearing rollers in the raceways, removable means on thefelly enclosing the bearings, said felly having a key removable thereon,and a rim having a key-way receiving the key therein, and removablemeans locking the rim on the felly. v r

In testimony whereof I affix my signature.
